2-/4-/6-/8-Channel, ±30kV ESD Protectors in μDFN
During an ESD event, the current pulse rises from zero
to peak value in nanoseconds (Figure 3). For example,
in a ±15kV IEC-61000-4-2 Air-Gap Discharge ESD
event, the pulse current rises to approximately 45A in
1ns (di/dt = 45 x 10 9 ). An inductance of only 10nH adds
an additional 450V to the clamp voltage. An inductance
of 10nH represents approximately 0.5in of board trace.
Regardless of the device’s specified diode clamp volt-
age, a poor layout with parasitic inductance significantly
increases the effective clamp voltage at the protected
signal line.
A low-ESR 0.1μF capacitor must be used between V CC
and GND. This bypass capacitor absorbs the charge
transferred by a +14kV (MAX13204E/MAX13206E/
MAX13208E) and ±12kV (MAX13202E) IEC61000-4-2
Contact Discharge ESD event.
Ideally, the supply rail (V CC ) would absorb the charge
caused by a positive ESD strike without changing its
regulated value. In reality, all power supplies have an
±30kV ESD Protection
ESD protection can be tested in various ways. The
MAX13202E/MAX13204E/MAX13206E/MAX13208E are
characterized for protection to the following limits:
? ±15kV using the Human Body Model
? ±14kV (MAX13204E/MAX13206E/MAX13208E) and
±12kV (MAX13202E) using the Contact Discharge
method specified in IEC 61000-4-2
? ±30kV using the IEC 61000-4-2 Air-Gap Discharge
method
ESD Test Conditions
ESD performance depends on a number of conditions.

power supply’s effective output impedance is 1 ? , then
by using V = I × R, the clamping voltage of V C increas-

es by the equation V C = I ESD x R OUT . An ±8kV
IEC 61000-4-2 ESD event generates a current spike of
24A, so the clamping voltage increases by V C = 24A ×
1 ? , or V C = 24V. Again, a poor layout without proper
bypassing increases the clamping voltage. A ceramic
